NPHP3 encodes nephrocystin 3 (1,330 aa). Required for normal ciliary development and function. Highest expression in Ovary (63.6 TPM) and Fallopian Tube (51.7 TPM).
NPHP3-related Meckel-like syndrome is associated with mutations in the NPHP3 gene on chromosome 3.
The NPHP3 protein participates in Myristoylated NPHP3 translocates into the ciliary membrane, UNC119B stimulates translocation of myristoylated ciliary cargo to the primary cilium, and RP2:ARL3:GDP:UNC119B dissociates pathways.
NPHP3 is classified as a druggable target with score 0.0.
Genetic testing for NPHP3 is available. Testing is considered confirmatory for diagnosis.
Phenotype severity distribution: 1 very common feature, 1 common feature.
Estimated prevalence: <1 in 1,000,000 (VERY_RARE).
No clinical trials have been registered for NPHP3-related Meckel-like syndrome.
6 publications have been identified in PubMed for NPHP3-related Meckel-like syndrome. Research spans Case Report / Case Series (50%), Review / Meta-Analysis (33%), and Epidemiology / Natural History (17%).
